LUBRICATOR FOR VEHICLE WHEELS.

APPLICATION FILED JAN. 12. 1911.

A TTORNEYS WITNESSES To all whom it may concern: i f

Be it known that I, Lnn L. S HELLINGER, acitizen of the United States, and aresident e of McGraw, in the county of Cortland and "State of New York, have invented a certain 1 new and useful Improvement in"Lubricators for Vehicle-Wheels, of which thefolj a lowing is a specification.

a My present invention relates generally to flubricators, and more particularly to lubricatorsfor wagon wheels and wheels of other ject being to provide a simple, inexpensive,

grand durable arrangement, the construction of whichadapts it for use under all conditions, and is such as to bring about the ad (vantages which I will presently describe.

' In the following description of my improvement reference is made to the accompanying drawing forming a part of this Specification, and whereina Figure 1 is a side elevation illustrating the practical application of my invention;

Fig. 2 is a vertical section on an enlarged scale, taken substantially on line 2-2 of Fig. 1, and I t Fig. 3 is another enlarged section through a portion thereof. 1 a Referring now to these figures, my in vention contemplates the provision of a lubricator including an elongated hollow feed stem 10, for extension through a conformable opening in the wheel hub A radially thereof,

at a point between the inner ends of certain [of the spokes B, the inner end-ofthe said a as to open onto the axle spindle extending I throug 7 the sleeve Gin use of the wheel.

f The hollow feed stem 10 is open at its a 4 the cylindrical barrel 11 of the lubricant holder, and is there threaded at 12 into a plunger 13 of considerably greater diameter than the tube 10, and having its annular face I threaded for engagement with the internally to thus cause relative longitudinal movement of'the plunger 13 with respect to the barrel,

l when the latter is rotated with respect to the said-plunger and the stem 10, the threaded connection of the plunger and barrel thus dispensing with threads upon the stem 10, in order to permit of a smooth unbroken cylindrical stem' of one diameter throughout at 5,5 lelast, the major portion of its length, as

1 The outer endof the barrell l of 'the lubricant, holder isaclosed-aby a cap 15 threaded thereinto and held against accidental 'dis placement by a; set screw 16, theinner end of the barrel 111 being: similarly closed by, coll ar 17 also threaded therein and held against displacement by a set screw 18, and through which the feed stem 10 passes, the lowerouter surface of which collar being in the form of a concaved cone with its central lowermost portion immediately around the stem 10 drawn to a relatively sharp edge 19 in snugly fitting sliding engagement with the said stem, so as to act as'a cutter upon the surface of the latter as the barrel 11 1 moves down thereon in each rotativefeed movement. I

In operation, with the barrel at its outermost position, the cap 15 is removed and the space within the barrel above the plunger 15 is filled with lubricant of suitable nature, and the cap 15 again secured in position so that, upon rotative movement of the barrel 11 to cause its inward movement upon the stem 10, a portion of the lubricant will be forced through the tube 10 and onto the axle spindle within the hub sleeve 0.

In the practical use of a device of this nature, it is obvious that the external surface of its stem 10 is exposed to incrusta tions by mud, ice, and other matter which would, in the absence of the cutting edge 19, seriously obstruct, if not absolutely prevent, movement of the holderdownwardly thereon. As my invention is constructed,

however, the collar 17 with its lower surface of the shape described, and with its cutting edge 19, operates to remove the said incrustations at each successive feed movement of the holder, so as to thus permit of ready operation of the lubricator under conditions which precludethe operation of those now in use, and considerably prolong its life.
